SPECIFICATION forming part of Letters Patent No. 660,920, dated October30, 1906. Application filed June 4, 1960. Serial No. 18,928. (No modelz)T aZZ whom it may concern.-

Be it known that 1, ERIC W. PALMoUIs'r, a citizen of the United States,residing at the city of St. Louis, in the State of Missouri, haveinvented certain new and useful Improvements in Body Bolsters forRailway-Cars, of V which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this specification.

My invention relates to improved body-bolsters for railway-cars whichare made of cast steel of box shape and the center bearing of which isstrengthened or supported by an in- I 5 tegral brace or braces.

My invention consists in features of novelty hereinafter fullydescribed, and pointed out in the claims.

Figure I is a top or plan view of my improved bolster. Fig. II isabottomview. Fig.

III is a view part in elevation and part in vertical section. Fig. IV isa detail vertical section showing a modification of the braces for thecenter bearing. Fig. Visa horizontal section taken on line V V, Fig. IV.

The bolster is made of cast-steel and is in box form, having verticalsides 1, a fiat top 2, and a bottom 3, inclined upwardly in bothdirections from the center. The bolster is hollow, and its top, bottom,and sides are preferably formed with openings 4 to lighten it. The flattop of the bolster receives the sills 5 of the car-body, and toprovide'for the attachment of the sills to the bolster the latter is 5formed with holes 6 in its top and bottom to receive connecting-boltsthat extend through the sills.

The bottom of the bolster is provided with integral side bearings 7 andan integralceno ter bearing 8, adapted to bear, respectively, againstthe side bearings and center bearing of a truck-bolster.

(Not shown.) For the purpose of strengthening the center bearing, uponwhich great strain is often exerted, I form integral with the bolster abrace which 5 may be in the form of a sleeve 9 through which theking-bolt passes, as shown in Fig. III, or it may be in the form ofwings 10, extending from a central hub on the center bearing to thebottom and sides of the bolster, as shown in Figs. IV and V. By thusbracing the center bearing it resists all pressure or strain that may bebrought upon it.

box form consisting of sides, a bottom, and a top; said bottom havingintegral side and center bearings and the center bearing beingstrengthened by an integral brace, substan- 7o tially as set forth.

A cast body-bolster for railway-cars of box form and consisting ofvertical sides, a flat top, and a bottom inclined upwardly in bothdirections from the center, said bottom being provided with ledges 12and center and side bearings and the center bearing being strengthenedby braces cast integral'with the bearing and the body of the bolster,substantially as described.
